Reheating pizza in the microwave often results in soft and soggy slices that can't begin to compare to the fresh pie you had before you stuck the thing in the fridge. According to home life blog the Simply Day, you can easily solve this problem with parchment paper.

Just like in the toaster, parchment paper adds a little extra mess-free crispiness in the microwave. Either place your pizza on a sheet or wrap it around the slice(s). You can heat the pizza as normal, but when you take it will be much closer to a fresh and crispy piece in a fraction of the time it would take to heat back up in a standard oven. DIY Life suggests this same trick works well in toaster ovens, too.
